cisco 2561XM router
sip trunk registered and working on IOS
several cisco 7940 ip phones
I have a problem with my ip phone system in that the redial button does not work when I dial sip numbers. If I call an internal number the redial works fine, but if I call a sip number and then try redail the section where the phone number displays is blank. This is the same on all the phones on the system.
Attached is a copy of some bits from my running config - maybe someone can see the cause there?
thanks for any help.
